sure nowadays you can rely on your usb wifi adapter and it is mobile you can use it on on another pc also, some are great on 2.4GHz band and fine at 5GHz in 802.11n-mode. PCI is more difficult to handle since you have to open the pc.

Thanks. Please tell , is it true , that putting wifi adaptor can enable 'virtual routers' also on the computer? I mean , wifi adaptor can receive internet from a wireless router and also tether data using virtual router softwares?

The easiest way to add Wi-Fi capabilities to a desktop computer would be through the use of a USB wireless adapter dongle. These are usually cheap ($10-20USD) and work quite well. Good brands are Netgear, TP-Link, Linksys/Cisco, Asus, and I have never had any trouble with Airlink 101.

Another way to enable Wi-Fi connection is through the use of a PCI or PCI-E slot on the motherboard. These may be better since many of these adapters would include an antenna, which may increase the signal strength being received. These adapters are generally $20USD or more.

Thanks. Pl tell : did you 'not' mention a word in the line ; "displayed in this new window, and will display if the adapter is wireless or not."

Sorry. To clarify, the "new window" is the "Network Connections" window in which it will display any installed network adapter, whether wireless or wired. It will display the name of the network adapters, such as Intel Pro 1000, and underneath would display if it is a wired Ethernet connection or wireless connection.

Most USB Wi-Fi adapters do not come with an external antenna, meaning that reception may not be as good, and pointing the adapter in a more appropriate direction to gain more signal strength may not be easy. Most PCI-E adapters have external antenna connections so that the antenna can be pointing towards the router location and have a better chance for stronger signal strength. The antenna connectors could also be capable of using external powered antennae to gain maximum signal strength from longer distances.

There are, however, some USB Wi-Fi adapters that do have antennae attached, though these are more expensive. In smaller areas that do not require higher levels of signal strength (remember that walls, obstacles, and other interference will reduce signal strength), standard USB Wi-Fi adapters should be fine.

Thanks . I have read your answer with care. Please tell , that a wifi adaptor also works to convert the computer into a virtual router ( using virtual router softwares like connectify and similar ) ? I mean to ask , it can receive internet as discussed , but it can also tether internet?

Yes, as Hovsep mentions, you can use Connectify to create a virtual router with either the USB adapter or PCIE wireless card.

Thanks. Please tell , a wifi adaptor can both receive and tether internet to another wifi-capable device?

I'm not sure if it can work for outgoing and incoming signals at the same time strictly through the Wi-Fi adapter. The question is why would you do this if there is already wireless signal that the devices can connect to? I'm having a hard time finding any information about this, and do not have experience with this specific scenario. Sorry I could not be of more help here.
